Introduction

Photodiodes (PDs) are semiconductor devices whose main purpose is to detect light. They are commonly found in the form of  integrated circuit chips, or as discrete components. The PD15-22C/TR8 is an  inverted-mode device specifically designed for photo detection applications. This article will discuss its application fields as well as its working principle.

Application Fields

The PD15-22C/TR8 is designed for photodetection such as detecting light intensity, detecting distance, rotational speed and displacement. The device works by using photovoltaic effects to convert light energy into an electric current. This current is then used to detect objects or detect the intensity of light.Most common uses of the PD15-22C/TR8 include barcode scanners, optical mice, optical switches, burglar alarms, proximity sensors, smart card readers, and biomedical applications. The device can also be used in data acquisition systems and process control systems in industry.

Working Principle

The PD15-22C/TR8 works by converting light into electrical current. This is done by photovoltaic effect, wherein photons of light are absorbed into a semiconductor material such as silicon, which then generates current.The PD15-22C/TR8 is an inverted-mode device, meaning the light is incident on the P-type (positive) semiconductor surface and results in a current flowing from the N-type (negative) surface to the P-type surface. This is different from a normal-mode device which has the reverse current direction.The device works in an \'open\' circuit configuration, meaning that the external load is not connected to the device and the photodetected current is measured. This configuration is usually used in photo detection applications where the current is used to detect objects or measure the intensity of the light.

Conclusion

The PD15-22C/TR8 is a photodiode device designed for photo detection applications such as barcode scanners, optical mice, optical switches, burglar alarms, proximity sensors, smart card readers, and biomedical applications. The device works using photovoltaic effects to convert light energy into electrical current. It is an inverted-mode device and works in an \'open\' circuit configuration which is usually used for photo detection applications.
